Treatment of petrochemical and coking wastewater
Thread Content
The petrochemical and coking industries are among the main sectors responsible for environmental pollution in China. At present, the challenges in treating wastewater from the petrochemical and coking industries in our country include the following aspects: The first challenge is the large volume of wastewater generated, along with its complex composition ； The second difficulty is the high ammonia nitrogen concentration ； The third challenge is that the coking wastewater generated by China’s coking processes has distinct local characteristics, which prevents some advanced foreign technologies from effectively addressing the issue of treating this wastewater in China. Our company adopts the basic process of the A/A/O system, combined with advanced oxidation and BAF processes, enabling the effluent to meet **first-class discharge standards. Friends who need help can contact me. There are several successful cases available for viewing. This post was last edited by johncom on 2009-4-1 08:46]
I don’t know what’s going on – it’s showing garbled characters The materials I sent can’t be uploaded either... Those who need materials or want to communicate can contact me at: rwp123@163.com. This post was last edited by rwphappy on 2009-3-19 09:45.]
Examples of treated coking wastewater: Last edited in this post by rwphappy on 2009-3-19 09:43]
Which company are you from? How can I get in touch with you?
Another ad poster. LZ, please provide some specific examples of engineering projects that have been handled, along with the relevant process parameters, so that everyone can learn from them; it might be more useful than what you’re saying.
There are technical parameter documents, but I can’t upload them at all. I’m helpless too. The main purpose is to provide friends with a design idea; if you need any help, you can contact me at 13269194457. My QQ number is 158703355 – we can discuss it in detail.
Could you briefly explain the water inlet and outlet conditions as well as the operation status of the project? We have water that needs to be treated here; could we learn from this approach?
Cyanide Ammonia nitrogen Petroleum compounds COD Volatile phenols pH SS
Inflow parameters (mg/l): 10–40 300 100 5000–9000 1100–1200 7–8 100
Outflow parameters (mg/l): <0.5 <5 <5 <60 <0.5 6–9 <30
Inflow parameters (mg/l): 10–40 300 100 5000–9000 1100–1200 7–8 100
Outflow parameters (mg/l): <0.5 <5 <5 <60 <0.5 6–9 <30
I currently have a project in the preliminary design stage; it involves treating wastewater from an oil refinery, with a flow rate of 180 cubic meters per hour. If you are interested, I would like to discuss in detail the treatment processes and investment requirements
I’ve given you my contact information; we can discuss this in detail
The wastewater from our facility is similar to what the original poster described, and we use roughly the same treatment processes; then why doesn’t the quality of the treated water meet the second-grade standards? I would appreciate it if an experienced expert could analyze this for me. Thank you!
Where are you from? I’m not sure what the problem is in your case; generally, the water output from a BAF process can approach or meet secondary treatment standards.
May I ask what advanced oxidation technology the original poster is using? I am promoting the use of ozone oxidation along with the reuse of ozone-rich exhaust gases for aeration in biological treatment tanks; perhaps we could work together (we don’t handle engineering work).

Another private discussion. Then what’s the point of a forum?
Personal questions are generally resolved privately. Such as business issues and so on. We address the common technical issues right here. The main issues that need to be addressed in the BAF process are: filter media technology, gas and water distribution as well as backwashing technology, and automatic control technology. Today, BAF is not only used for municipal sewage treatment but also in the fields of petroleum, chemical industry, and coking wastewater treatment. Based on the performance of various sewage treatment projects undertaken, the quality of the treated water meets standards that are even better than those specified in the designs.

The BAF should belong to the third generation of biofilm reactors; it not only possesses the advantages of biofilm process technology but also serves as an effective means of spatial filtration. Currently, the renovation of water treatment plants is highly efficient; in terms of treatment performance and operation, it is also quite effective for dealing with wastewater from the petrochemical and coking industries.
The guarantees sound good, but can they actually meet the standards? Can I go and visit?
We have multiple successful cases for you to visit, and we can ensure that the water quality meets the required standards
Do you have any projects in Shandong? I want to go take a look. If possible, please contact: taihetianrun@126.com
In my opinion, BAF is not very suitable for use in the petroleum and petrochemical industry; firstly, the wastewater from this industry contains oil, which is harmful to biological membranes. The water supply for the second petroleum and petrochemical industry has poor biochemical properties, and its quality is uneven; under normal conditions it is fine, but once the water quality becomes unstable, it is difficult to meet the required standards. Are there any highly successful cases in Jiaohuashui? Let me introduce it to everyone.
